Final answer:
The health professional who works under a physician performing routine physical exams, ordering tests, and treating minor injuries is a 3) Physician Assistant. They complete a master's degree and are nationally certified. Their role is distinct from medical assistants, nurses, and pharmacists, who have different scopes of practice.
Step-by-step explanation:
The health professional that typically works under the supervision of a physician to perform routine physical exams, order basic diagnostic tests, and treat minor injuries is a Physician Assistant (PA). PAs are trained to provide a wide range of medical services, from patient education and preventive healthcare to the diagnosis and treatment of acute and chronic diseases. Physician Assistants are required to complete a master's degree and must pass a national certification exam.
It is important to note that a Medical Assistant usually performs administrative and clinical tasks, but does not have the training to conduct physical exams or treat injuries to the same extent as PAs. On the other hand, a Nurse can vary in their scope of practice based on their qualifications (LPN, RN, NP), while Pharmacists primarily focus on medications, their effects on the body, and counsel patients on drug use. In none of these roles do individuals work quite like a Physician Assistant under the direct supervision of a physician.
